Factory resetting Galaxy S3, question on backing up

So, I'm factory-resetting my S3. Want to wipe it clean and start with a fresh OS (for various reasons). I've used Super Backup to backup my apps, my SMS messages, call logs, and calendar. All of these are on an external card.

My only concern is regarding the apps - after resetting, can I simply install the backed up .apks and get my apps back?

I believe that the app data is included. What I have in the external backup folder are individual .apk files, and corresponding folders called com.appname that contain subdirectories titled var/lib/cache/conf/files/etc.

I assume those are appdata folders I'd need to restore the apps on a fresh OS installation?

Well.. Try doing this:
Find an app / or install an app that uses app data.. Like a notepad / to do list app.

Create some content... Make a list / draw something... just to create some data..... Then back up the app and data with the same tool you used before.
After you made the backup Uninstall the app from your phone and then try to restore the app from your backup.
Check for the data... Then you will know for sure if it works
